Scorpius,

Shut down your system, open up the case and make sure the RAM is firmly
seated into the socket...It should lock into place if seated properly.

I did as you said but my computer is still telling me that the 512 memory I
installed is only 256! Is it possible that the manufacturer made a mistake in
packaging?
